rhe invention relates to vehicle wheels and refers particularly to thedisk type. One of the objects of the invention is the provision of adisk wheel in which the brake drum is secured to the hub to form a unittherewith and the disk is detachably secured to the hub and braced bythe brake drum.

With this as Well as other objects in View, the invention resides in thenovel features of construction and combinations and arrangements ofparts as more fully hereinafter set forth.

In the drawings:

Figure l is a side elevation of a portion of a disk wheel embodying myinvention;

Figures 2 and 3 are cross sections respectively on the lines 2 2 and 3 3of Figure l;

Figure 4 is a side elevation of the spacer;

Figures 5, 6 and 7 are cross sections respectively on the lines 5 5, 6 6and 7 7 of Figure 4;

Figure 8 is a View similar to Figure 2 but showing a modifiedconstruction of wheel.

l is the hubof the vehicle wheel having the annular flange 2. 3 is thebrake drum having the annular flange 4 extending transversely of theaxis of the hub and spaced from the-annular flange 2 and alsoterminating in the annular foot flange 5 engaging lthe periphery of thehub. 6 is an annular spacer between the annular flanges 2 and 4. Thebrake drum forms a unit with the hub,l it being secured thereto by thebolts 7 which extend through the annular flanges 2 and 4 and the spacer6, and have the heads 7 engaging in the annular flange 2, and also bythe nuts 8 engaging the inner ends of the bolts and abutting the innerside o-f the annular flange of the brake drum. Each of the bolts alsohas a polygonal portion 7 2 engaging 1n a correspondingly shaped recess9 in the spacer as shown in Figures 3, 4 and 7 particularly, to preventrotation of the bolt while threading the nut on or off'.

The'wheel body is formed by the disk l() having-at its inner edge theannular radially extending portion 11 terminating in the annular footflange 12 engageable with the periphery of .the hub. The radial; portion11 extends adjacent to the outer side of the annular flange 2 of thehub, and is detachably secured thereto by means of the bolts i3extending transversely of and preferably cast in the spacer 6 and havingtheir ends e extending through the annular flange 4 of the brake drum,the annular flange 2 of the hub, and the radial portion 11 of the disk,the portions of the bolts engaging the annular flange 2 and radialportion 11 being enlarged. Nuts 14 threaded upon the inner ends of thebolts clamp against the inner side of the brake drum annular vflange,and nuts l5 threadedly engaging the outer ends of the bolts clamp thedisk against the flange of the hub. An end plate 16 is detachablysecured upon the hub by the hub cap 17, this plate inclosing the nuts 15and extending adjacent to the disk 13 radially therebeyond.

For the purpose of making the structure'V substantial the portion ofthehub engaged by the foot flange upon the disk, is tapered and the footflange is firmly forced thereon,

In the modified construction shown inv Figure 8, the wheel has the samearrangement as that shown in Figures 1 and 2 with the exception that thedisk 36 is detachably secured to the outer edge ofthe annular flange ofthe brake drum 37 by the cap bolts 38, by means of which the innerportion/of the wheel is made rigid.

, From the above descriptiomit will be readily seen that l have provideda disk wheel in which the brake drum bracesthe disk forming the wheelbody to form a rigid construction between the periphery of the brakedrum and the hub. Also, that the resilient portion of the wheel isbeyond the brake drum periphery and is iocated inside ot the contraiiane of rotation or tbe piane of impact. iV oreovera tiie disk isdetachable from the hub and brake drum unit.,

iii/'hat "i ciaim as my invention is:

1. iin a vebicie Wiieei, the combination Witb. the hub, oi a member uponand formino; a unit With said hub, a disk having a portion spaced fromsaid member and a second portion spaced radiaiiy outward from saidrstmentioned portion and in contact with said member, means tordetaciiabiy securing said first mentioned portion to said but)j and anend piate detacbabiy secured to said hub independently oi'said securing1means and contacting' with said disk radiaiiy beyond said hub -forreinforcing tbe inner portions of the disk.

2. in a Vehicle wiieei., tbe combination with the hub having an annuiar"dange, of a brake drum mounted upon said hub, a spacer between saidbrake drum and annuiar tiamge means i'or securing` said brake drumspacer and annuiar tiange to eacb. other to form a unit, a disk baringan inner portion spaced 'from said brake drum and detacbabiy secured vto said annular tiange, a portion positioned radiaiiy beyond said innerportion andl detacbabiy engaging said brake drum, and an intermediateportion means incinding boite secured to said' spacer for detaohabiysecuring said inner portion to said annular Hangs, and means conceaiingsaid securing means and engageabie with said intermediate portionradially beyond said annuiar tiange tor reiniorcing the inner portionsof said disk.

3. in a vehicle Wbeei., tbe combination with the buio having a taperedportion, of a member upon and `forming1 a unit with said hub? a diskhaving an inner portion spaced trom said member and engageabie with thetapered portion ot said hub, said disk aiso having another portionspaced radially beyond said inner portion and in contact with saidmember., means engaging said inner portion for detaciiabiy securing;-said disk to said member and an end piate detacbabiy secured upon saidhub and conceaiing said securing means said end plate having a portionContactin@ with the inner portion ot said disk in Contact with thetapered portion or" said hub and another portion contacting with saiddisk radially beyond said hub.

in a Vehicie Wbeei7 tbe combination with the iiub having an annuiariiange, oi a brake drum mounted upon said hub and spaced iongitudinailythereoi':` irom said annuiar flange7 means :tor securing said brake drumto said annular flange to `form a unit a disk having an inner portiondetaciiabiy secured to tbe opposite side oiizsaid annuiar flange and aportion positioned radiaiiy beyond said inner portion in contact withsaid brake drums means tor detachabiy securing said inner portion tosaid annular dange, an end piate de- Leonesa tacbabiy secured to saidtmb independentiy ot said securing means and contacting with said diskradialiy beyond said annuiar flange and a hub cap upon said hub torsecuring said end plate to said hub.

5. in a vehicle Wheei, the combination Twith a hub, of a member mountedupon said tmb9 a disk bai/ing' a portion engageabie with said iiub andspaced from said member and a seeond portion spaced radiaiiy outwardfrom said iirst men ioned portion and in contact with said member7 meansfor detachabiy securing said iirst mentioned.' portion to said buio, anend piatebaving a portion sleeved upon said hub and abutting said iirstmentioned portion oi said disk7 said end piate ,having another portioncontacting with said disk beyond said hub and conceaiing said securing,vmeans, and means other than the means aoresaid for detachabiy securingsaid piate to said hub.,
